79 2018-03-01 - 6731f60598 - lavu 56.8.100 - frame.h
80 Add av_frame_new_side_data_from_buf().

104 options. Introduce "listen_timeout" as replacement for the current "timeout"
105 option, and "user_agent" as replacement for "user-agent". Once the deprecation
106 is over, the old "timeout" option will be removed, and "stimeout" will be
107 renamed to "stimeout" (the "timeout" option will essentially change semantics).
109 2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
110 Deprecate AVFormatContext filename field which had limited length, use the

123 Explicitly make avformat_network_init() and avformat_network_deinit() optional.
124 If these are not called, network initialization and deinitialization is
125 automatic, and unlike in older versions, fully supported, unless libavformat
126 is linked to ancient GnuTLS and OpenSSL.
128 2018-01-16 - 6512ff72f9 - lavf 58.4.100 - avformat.h
129 Deprecate AVStream.recommended_encoder_configuration. It was useful only for

132 2018-01-05 - 798dcf2432 - lavfi 7.11.101 - avfilter.h
133 Deprecate avfilter_link_get_channels(). Use av_buffersink_get_channels().
135 2017-01-04 - c29038f304 - lavr 4.0.0 - avresample.h
136 Deprecate the entire library. Merged years ago to provide compatibility
137 with Libav, it remained unmaintained by the FFmpeg project and duplicated
138 functionality provided by libswresample.
140 In order to improve consistency and reduce attack surface, it has been deprecated.
141 Users of this library are asked to migrate to libswresample, which, as well as
142 providing more functionality, is faster and has higher accuracy.
144 2017-12-26 - a04c2c707d - lavc 58.9.100 - avcodec.h
145 Deprecate av_lockmgr_register(). You need to build FFmpeg with threading
146 support enabled to get basic thread-safety (which is the default build
149 2017-12-24 - 8b81eabe57 - lavu 56.7.100 - cpu.h

184 Add AV_PIX_FMT_OPENCL.
186 2017-11-11 - 48e4eda11d - lavc 58.3.100 - avcodec.h
187 Add avcodec_get_hw_frames_parameters().

202 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated
203 API only (avcodec_decode_video2/avcodec_decode_audio4). The new decode APIs
204 (avcodec_send_packet/avcodec_receive_frame) always work with reference
207 2017-09-21 - 6f15f1cdc8 - lavu 55.76.100 / 56.6.0 - pixdesc.h
208 Add av_color_range_from_name(), av_color_primaries_from_name(),

244 DXVA2 and D3D11 hardware accelerated decoding now supports the new hwaccel API,
245 which can create the decoder context and allocate hardware frame automatically.
246 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
247 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

255 2017-06-14 - d59c6a3aeb - lavu 55.66.100 - hwcontext.h
256 av_hwframe_ctx_create_derived() now takes some AV_HWFRAME_MAP_* combination

290 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
291 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
292 set the Cuda device handle.
294 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

318 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
319 (via an entry named "rotate"). Use av_stream_get_side_data() with
320 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
321 av_display_rotation_get(). The same is done for muxing. Instead of adding a
322 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
323 to be added to the AVStream.

335 Add AVIO_SEEKABLE_TIME flag.

338 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
339 bump, and libavformat will behave as if it were always set.
340 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
342 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

356 bound_bottom, padding) to AVSphericalMapping.
358 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
359 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
360 native decoder format. (The default value is not changed.)
362 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
363 Remove requirement to use AVOption or accessors to access certain fields
364 in AVFrame, AVCodecContext, and AVFormatContext that were previously
365 documented as "no direct access" allowed.

382 2017-01-17 - 2a4a8653b6 - lavc 57.74.100 - vaapi.h
383 Deprecate struct vaapi_context and the vaapi.h installed header.
384 Callers should set AVCodecContext.hw_frames_ctx instead.

483 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
485 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be

553 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

558 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
559 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
560 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
561 The default value for this option will change to "ass" at the next major
562 libavcodec version bump.
564 The current default is "ass_with_timings" for compatibility. This means that
565 all subtitles text decoders currently still output ASS with timings printed
566 as strings in the AVSubtitles.rects[N]->ass fields.
568 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
569 timing is limited to a 1/100 time base, so this is relevant for any subtitles
570 format needing a bigger one), ease timing adjustments, and prevents the need
571 of removing the timing from the decoded string yourself. This form is also
572 known as "the Matroska form". The timing information (start time, duration)
573 can be found in the AVSubtitles fields.

3021 When the lock manager is registered, FFmpeg is guaranteed to behave
3022 correctly in a multi-threaded application.
3024 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3025 av_free_packet() is no longer an inline function. It is now exported.
3027 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3028 Please use NULL instead. This has been supported since r16506
3029 (lavf > 52.23.1, lavc > 52.10.0).
3031 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3032 The old decoding functions are deprecated, all new code should use the
3033 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3034 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3035 argument instead of a const uint8_t *buf / int buf_size pair.
3037 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3038 Introduce the av_fifo_space() function.
3040 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3041 Move AVPacket declaration from libavformat/avformat.h to
3042 libavcodec/avcodec.h.
3044 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3045 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3046 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3047 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3048 PIX_FMT_BGR32_1 are now macros.
3049 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3050 Re-sort the enum PixelFormat list accordingly.
3051 This change breaks API/ABI backward compatibility.
3053 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3054 Add the enum PixelFormat values:
3055 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3056 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3058 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3059 The Mersenne Twister PRNG implemented through the av_random* functions
3060 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3063 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3064 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3065 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3066 and av_fifo_realloc2.
3067 In addition, the order of the function arguments of av_fifo_generic_read
3068 was changed to match av_fifo_generic_write.
3069 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3070 applications, they may not use sizeof() or directly access members.
3072 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3073 Introduce a new metadata API (see av_metadata_get() and friends).
3074 The old API is now deprecated and should not be used anymore. This especially
3075 includes the following structure fields:
3076 - AVFormatContext.title
3077 - AVFormatContext.author
3078 - AVFormatContext.copyright
3079 - AVFormatContext.comment
3080 - AVFormatContext.album
3081 - AVFormatContext.year
3082 - AVFormatContext.track
3083 - AVFormatContext.genre
3086 - AVProgram.provider_name
